Square D QOU230VH miniature circuit breaker

This Square D QOU230VH is a high-interrupting-capacity miniature circuit breaker rated at 30 amperes. It uses a two-pole design for single-phase 120/240 volt AC systems and is compatible with QO series panelboards. The breaker suits air conditioning, refrigeration and heating equipment.

Surface or DIN rail mounting with reversible lugs

The unit mounts on a surface or DIN rail and features a toggle actuator for manual operation. Its slotted box lug terminals accept reversible line and load connections, simplifying wiring in either direction. A 48 volt DC rating adds flexibility for mixed-voltage control circuits.

22 kA interrupting rating at 120/240V AC

The breaker carries a maximum AIR rating of 22 kiloamperes at 120/240 volts AC, defining its ability to clear high fault currents safely. Installations requiring a higher interrupting capacity must select a different device. Buyers needing a single-pole or lower-amperage breaker should choose another model.
